The latest GPLv2 version of gmp is 4.2.1, which was released in 2006/05.

This GPLv2 recipe is written in clean house approach, w/o looking at
either v3 source code and recipe.

One patch (disable-stdc.patch) is added, which is also written from
scratch and licensed under GPLv2

test with 'calc' which is shipped by gmp package

+# "extern inline" in traditional gcc means that the function should be

+# gmp checks "--std=gnu99" to use C99 convention however it internally

+# by mainly .c files and finally lead a flood of redefinition function
+# errors when linking objects together.
+#
+# So disable C99/ANSI detection to stick to tranditional gcc behavior
